Liquid Level Sensor for Hydrostatic Level and Temperature Measurement

October 10, 2012

The AST45PT liquid level sensor provides two independent 4-20mA output signals for a level signal and a temperature signal. Users benefit from a single instrument installation, saving time and money. With submersible cable being one of the more costly options for deeper level requirements, a single measurement point is a cost effective solution. With measurement ranges from 1 PSI (27.68" water column) to 100 PSI (230.67'' water column), the AST45PT appeals to a wide range of applications. AST offers five temperature ranges and eight cable length options to make integration simple. Each AST45PT comes with a removable nose cone. While it is installed on the sensor to protect the sensing element from damage during submersion, users have the option to remove it to access the 1/4" NPT male pressure port. For example, if a customer is looking to take a pressure measurement externally from a tank in a flood prone area, the AST45PT will be an ideal solution. Additionally, the sensor is designed with a ½" NPT conduit fitting at the electrical connection. Conduit can be installed over the cable to provide rigidity in turbulent tanks or protection from sharp objects.
